Most organisms (including humans) developed daily rhythms in almost every aspect of their
body. It is not surprising that rhythms are also related to affect in health and disease. In the …

The evolution of endothermy in birds and mammals was one of the most important events in
the evolution of the vertebrates. Past tests of hypotheses on the evolution of endothermy in …

Animals should time activities, such as foraging, migration and reproduction, as well as
seasonal physiological adaptation, in a way that maximizes fitness. The fitness outcome of …

Animal internal state is modulated by nutrient intake, resulting in behavioral responses to
changing food conditions. The neural mechanisms by which internal states are generated …

Starvation is defined as a failure to consume food following an extrinsic limitation. By
focusing on arthropods, I provide here a detailed review of how starvation affects foraging …

Finding food and remaining at a food source are crucial survival strategies. We show how
neural circuits and signaling molecules regulate these food-related behaviors in …

The circadian clock in peripheral tissues can be entrained by restricted feeding (RF), a
regimen that restricts the duration of food availability with no calorie restriction (CR) …

Background The ability to adapt behavior to changing environmental circumstances, or
cognitive flexibility, is impaired in multiple psychiatric conditions, including anorexia nervosa …

Daily variations in behaviour and physiology are controlled by a circadian timing system
consisting of a network of oscillatory structures. In mammals, a master clock, located in the …

Objective The existence of seasonal changes in energy metabolism is uncertain. We
investigated the relationship between the seasons and spontaneous physical activity (SPA) …
